The museum is on the site of the original headquarters of the Eagle Lock Company. Later, it became Plymouth's Town Hall, which had a jail in the 1800s. The cell door is on display, complete with a ball and chain!
​
Across the street from the museum is the original location of the Eagle Lock factory, founded in 1854. Some buildings still remain visible.
Located down the street from the museum is the Eli Terry, Jr. Water Wheel, listed on the National Register of Historic Places.
​
Terryville is probably the only town in the United States with a Water Wheel on its Main Street!
​
The Water Wheel is 22’ in diameter and 7’ across. It supplied 8 horsepower to run the factory. It is owned by the Plymouth Historical Society and was restored in 1991. The surrounding area was later renovated by the town’s Historic Properties Commission.
​
Eli Terry, Jr. began making clocks here in 1824. The Water Wheel converted the energy of the Pequabuck River to power the lathes, presses, and saws in the factory. In 1832, Terry partnered with lock maker Stephen Bucknall of Watertown, Connecticut, and began manufacturing locks. For a while, both clocks and locks were produced. Terry died in 1841 at the age of 42. In 1851, the factory, then owned by the Lewis Lock Company, burned down, but was rebuilt, including the Water Wheel. It is believed that the iron hardware of the original wheel was reused.
​
In 1854, James Terry, son of Eli Terry, Jr., formed the Eagle Lock Company. The firm became the dominant manufacturer of cabinet locks, trunk locks, padlocks, and specialty locks in the world. Many of these locks are on display in the Lock Museum of America.
​
There are interpretive signs that explain how the Water Wheel worked. A path on the hill behind the benches leads to the remains of an earthen dam. You can see the stone tunnel that carried the water from the dam to the Wheel when the iron gate was opened. The gate is on the upstream side of the dam.
